WATCH- REG U LA'TOR.

SPECIFICATION forming part of Letters Patent N0. 398,987, dated March 5, 1889.

Serial No. 271,889. (No modeld To all whom it may concern:

Be it known that I, CHARLES TEsKE, a clti- 5 zen of the United States, residing in the city 1 and county of Hartford and State of Connectii out, have invented certain new and useful Improvements in atch-Regulators, which improvements are fully set forth and dei scribed in the following specification and illustrated in the accompanying two sheets of drawings.

The immediate object of myinventionis to i provide a regulator of simple construction by means of which a fine adjustment of the hair-spring may be obtained. I have also kept it in view to so construct my new device that it may be readily adapted to watches of modern construction without any material changes being required in such watches.

' In the drawings hereto annexed, Figure 1 shows a regulator of my preferred form as attached to the upper plate of an American watch, said figure being somewhat enlarged. The several figures from 2 to 19 are drawn to a scale twice the size of Fig. 1. Fig. 2 is a vertical section of the regulator-arm and its adjusting mechanism on line azccof Fig. 1. Fig. 3 is an elevation of the toothed rack b and its attached traveler from the outer (or left-hand) side of Fig. 1. Fig. 4 is a plan View of the same parts, and Fig. 5 a similar view having a straight rack and graduated plate substituted for the curved corresponding parts in the preceding figure. Figs. 6 to 12 (both inclusive) illustrate various modified methods of connecting the traveler c with the regulator-arm D. In Figs. 13 and 14 I have dispensed with the toothed rack and depend on friction to move the traveler forward or backward. Fig. 15 is a cross-section of the bar and traveler on line 22' of Fig. 14. In Fig. 16 I have dispensed with the plate a shown in the preceding forms of regulators and have graduated the face of rack b. Fig. 17 shows a plan view and central vertical section of a graduated disk intended to be used with a 1 plain curved bar. Fig. 18 is a side elevation of a rack having integral projections or legs that serve to raise the rack proper above the watch-plate. Fig. 19 is a plan view of a graduated rack having the traveler-block secured thereto and actuated by an endless l screw or worm instead of a pinion-gear, as shown in the preceding figures.

The reference-letter A denotes the upper plate of a watch; l), the hair-spring. and C I the balance-wheel.

I) indicates the regulator arm or lever.

The several parts thus far named are supposed to be made and connected in the manner common to this class of watches, and requires 110 detailed description.

Referring to Figs. 1, 2, 3, and a, the letter a indicates a plate formed,preferably, as an arc of a circle whose center is also the center of the balance-wheel C, said plate being graduated substantially as shown, and marked at each end to indicate in which direction the regulator-a rm must he moved to increase or reduce the speed of the watch.

Z) denotes a corrcspondingly-curvwl toothed bar, whose body portion is formed with a downwardly-projecting longitudinal rib, b. This raclebar is clamped to the plate a and to the watch-plate A by screws cc, which pass downward through said parts and are tapped into said watch-plate. In order to elevate the rack-bar Z) above the graduated plate, (for reasons hereinafter seen,) I provide hollow posts (I (Z, as in Fig. through which the screws 0 pass, or form said rack-bar with integral legs L as seen in Fig.

The letter e denotes a traveler-block having its body portion slotted transversely to fit the rib h of the described rack-bar, and having its outer end pointed to traverse the grad uated scale on plate a, and thus serve as an index or guide during the act of regulating the watch. The traveler-block e is perforated near its index end to receive a stud or pivot bearing a 1i inion-gear,f, that meshes with the toothed rack Z), and is also slotted on its posed end, so that a screw-driver or knifeblade may be used, if necessary, to rotate said pinion-gear. The inner end of the travelerblocl: I prefer to form substantially like the jaws of a pair of calipers, as shown at g in Figs. 1, 2, and 4:, said jaws being opened or separated a distance sufficient to receive the 1: end of the regulator-awn D.

Assumingthat we have regulator parts made and assembled as described, and as shown in Fig. 1, it will be readily understood that if away at one side.

the pinion-gear f be rotated the traveler-block 9 will be advanced on rack-bar b, and the regulator-arm D correspondingly moved.

Thus far I have described the rack-bar and the graduated plate a as curved; but it is not absolutely necessary that they be so formed in order to work satisfactorily. If desired, they may be made straight, as in Fig. 5, the only difference in the action of the complete device being that instead of traveling together in the same are the positions of the regulatorarm D and the caliper-shaped jaws of the traveler-block are relatively changed as said block is moved along the bar b; but the result, so far. as the adjustment of the hairspring is concerned, is the same with either form of rack.

Various slight modifications of the principle of my invention may be made without departing from the spirit of said inventionas, for example, the manner of connecting the traveler-block and the regulator-arm D may be varied as circumstances or judgment may direct. The several forms of connections illustrated in Figs. 6 to 10 (both inclusive) are practically the same, varying only in the shape of the connecting end of the traveler-block. In Figs. 6, 7, and 8 the jaws or operative portions engage the regulator-arm in the same manner, but are formed, respectively, as stirrup shape and rectangular. In Fig. 7 said rectangle is opened at one of its angles, While that of Fig. 8 is opened at the side to receive the regulator-arm.

Fig. 9 shows the traveler as grooved to receive the said regulator-arm and provided with a screw, 72 whose head is flattened or out After the regulator-arm has been entered in the groove, the screw h is partially rotated to overhang the groove and prevent the displacement of said arm.

In Fig. 9" the end of the traveler is simply forked or split to receive said arm.

In Fig. 10 pins 2' are provided-one on each side of the regulator-armand in Fig. 11 a single pin, 1", is provided, on which the perforated end of said arm is pivoted.

In Fig. 12 the construction of the engaging ends of said traveler and regulator-arm are the reverse of that shown in Figs. 1 to lthat is to say, the end of the traveler is simply fiattened or drawn out thin, while the end I of the regulat )r-arm is shaped as caliper-jaws and rack-bar should be so finely fitted and adjusted that there may be no tendency to slip on each other during the act of adjustment.

The graduated plate a may, if desired, be dispensed with, in which case the rack-bar b may be secured directly to the watch-plate A, and graduated, as in Figs. 16 and 19. When so constructed, a pointer or index, m, should be provided on the traveler-block, that proj cots upward to engage and traverse the graduated face of the rack-bar.

Fig. 17 illustrates the pinion f as provided with an enlarged head or disk, a, graduated on its exposed face near the edge. When the pinion is so provided, the scale on the rack bar is omitted. In place of the pinion-gearfi equally fine adjustment of the traveler-block along the rack-bar may be attained by sub stituting for said gear an endless screw or worm, 8, (see Fig. 19,) which engages the teeth of the rack-bar. \Vhen so formed, the end of the pivot that supports said worm is slotted, and may be readily operated by a small screwdriver or similar tool.

A device embodying the essential features of my described invention may be cheaply produced and attached to watches, and is believed to meet all the requirements of a perfect regulator.

I am aware that it is not broadly new to move the regulator-arm of a watch by means of a rack and pinion or worm, and to provide the same with an index.

Having described my invention, I claim 1. In combination with the regulator-arm of a watch, a fixed bar having on its body por- 2. In combination with the regulator-arm of a watch, a fixed bar adjacent thereto, a

traveler-block fitted to slide longitudinally on said bar, having its inner end connected to said regulator-arm and its outer end pointed to form an index, a disk journaled in the index end of said traveler-block with its perimeter in engagement with said bar, and the graduated scale on the outer side of said bar, over which scale the pointed outer end of the traveler-block traverses, substantially as described, and for the purpose specified.
